Local privilege escalation through undisclosed ReFS flaw
Published Oct 10, 2023 · Updated Apr 14, 2025
Out-of-bounds read in Microsoft ReFS on affected Windows releases allows local users to elevate privileges via unspecified vectors. Microsoft has not disclosed the affected ReFS code path or how it reads beyond an intended buffer boundary. Exploitation requires local low-privileged access and can grant control beyond the user's existing permissions.
